' To all whom it may concern:

' of the arrows.

Be it known that I, SOLOMON Mnnxs'rnm, a citizen of the United States, and a resident of the city, county, and State of New York, have invented a new and useful I mprovcment in Pneumatic Sweepers, of which the following is a specification.

The object of my invention is to provide a sweeper or cleaner of the neumatic e which will be portable, dura 1e and simp e, and capable of operation, either manually or by power, as may be desired. This object is accomplished by my invention, one embodiment of which is hereinafter set forth.

For a more particular description of my invention, reference is to be had to the accompany g drawings forming a part hereof, in which,

tion by means of radially each of which extends from a point near the 'Throughout the various views of the 'lllgS 9 which are pivotally connected with the nozzle 10 and are preferably adjustably connected by a slot and bolt connection with a collar 11 on the pipe 12 which extends diagonally and upwardly from the nozzle 10 to a T-connectlon 13 to which the bar or pipe 8 runs.

The collar 11 is connected with a similar collar 14 on the bar 8 by a horizontally disposed rod 15, so that the rod 15, the pipe 12 and the bar 8, with their connecting parts form a triangle which is a rigid and stable construction under all circumstances to support the other parts of the pneumatic cleaner. The collar 11, as above stated, is connected with the bearings 9 by a bolt 16 which passes through a slot 17 in these bearings 9 so that the nozzle 10 may be placed, by adjustment, as near the surface to be cleaned, as desirable.

The connection 13 has four openings. Ono connects with the pipe 12, one with the bar 8, the third is an opening covered with a screw-cap 18 which is provided so as to give convenient access to the interior of the apparatus, or to permit a cleaning device for walls to be attached, and the fourth opening is adjacent to the blower 19 which is secured to the pipe 12 which passes entirely through the connection 13, thls pipe 12 being perforated opposite the projection on which the cap 18 15 located.

The blower 19 consists of a disk 20 with a central perforation which is screw-threaded (see Fig. 4) and secured to the pipe 12 and its outer edges are also perforated to permit the cap screws 21 to pass therethrough, which cap screws enter the flanges of the casing 22 in which the fan 23 is mounted to rotate. This fan 23 consists of two parallel disks 24 and .25 which are held in rigid reladisposed veins 26 center to the circumference and these veins 26 are secured by. means of perforated ears l 27 through which small rivets or screws are passed. The disk. 24 is provided with a large central perforation, a little larger than the bore of the pipe 12 and the disk 25 has a other wall is secured thereto by cap screws 32 or in any other suitable manner. Studs 33 are secured in the walls of the housing in an suitable manner, to which arms 34 carrying a handle 35 are secured, as shown in Figs. 3 and 8.

The axle 31 is preferably made square in cross section at one end and fitted to the armature of a motor 36 which is supported by a bracket arm 37 extending from the easing 30. This is-the preferred construction,

but others may be employed as described below.

In the casing 22 is a nozzle or passage 38 connected to a pipe 39 which leads to an air filter 40. The ust and air are blown by the fan 23 through the nozzle 38 and pipe 39 into the filter or box 40 through the nozzle 41 that leads into the lower chamber thereof.

The filter 40 may be given any suitable shape but is preferably made substantially as shown, so as to fit securely and firmly in the machine 1. Its lower wall orfloor is horizontal and is provided with two clips or pairs of depending lugs 43, one located at each end, which are adapted to be secured to the rod 15 by means of bolts 44 or other suitable means, or these bolts may be omitted. A similar clip 45 near the top of the filter 40 secures the same to the bar 8, thereby firmly fixing the filter 40 in place. This filter 40 is also provided with a nozzle 46 covered by a screw cap 47 which may be removed when desired to withdraw or supply.

water. for the filter, the said water bemg designated by the character 48.

Above the water, 48 and terminating just above the same, is the diagonally extending baflie plate 49 which covers the nozzle 41 and forms the up er wall of the chamber- 42. The upper wa l 50 of the filter 40 runs parallel to the pipe 12 and is provided with an opening in which is mounted a gauze 51 which is held in place by means of suitable flanges 52. Below this gauze and running at an angle thereto and nearly parallel therewith, is a cloth 53 mounted between two metal holders 54' and 55 respectively, see Fig. 9, each fitted snug in the chamberbelow the gauze 51, so that all air passing through the gauze 51 must also pass through the cloth 53.

In Figs. 1 and 2 the shaft 28 is provided with a bevel gear 56 driven by second gear 57 which is mounted on a shaft to which the I crank 58 is attached and by which it is driven. In this embodiment of my invention the machine is manually driven. The bevel gear 57 is protected by the guard 59 suitably supported from the casing 22 of the blower. I

In Figs. 11 and 13, is shown a slightly modified form of" manually operated driving mechanism, similar to the structure shown in Figs. 1 and 2, but differing slightly. In this instance the crank 58 is mounted on a shaft held by arms 60 bolted to the casing 22 of the blower, and the handle 61 is also supported by two arms 62 similarly supported.

In Figs. 14 and 15- is shown the same structure as in Figs. 11 and 13, except that the manually driven devices are removed and a motor 63 replaces them, this motor 63 being supported by bracket 64 which is much the same as'bracket 60 except that it has only one web where the motor is secured and it is not provided with bearings.

In Fig. 12 is shown a structure ready to receive either a motor or a manually operated device.

The operation of my improved cleaner will be readily appreciated from the oing.

' The blower 19 is set in operation either by an electric motor, the preferred manner, or manually, as desired, and when at full speed, the parts being as shown in Fig. 1, the cleaner is shoved on its rollers over the floor, the nozzle 10 being close to the part swept. The suction of the air through the pipe 12 causes the dust to pass with the air through the nozzles 10 and pipe 12 into. the blower 19 and thence through the pipe or tube 39 and nozzle 41 into the air filter 40, where the dust and air are thrown against the partition or bafiie 49, and thence down against and into the water 48 in the bottom of the chamber 42. The air passesbetween the baffle and the water, displaces the water, if necessary and when so passing it is almost freed from its dust. However, a small quantity of dust remains which is caught on the cloth 53 which cloth is kept 'damp and is renewed fromtime to time as it gets dirty. The air passing through the 010 53, and the gauze 51 is thoroughly cleaned and purified so far as dust is concerned.

v The pneumatic cleaner is entirely self-contained, except that when an electric motor is employed, a cable must be connected with a fixture so that electricity may be supplied, but as this cable is light and easily handled, it will not in any way interfere with the movements of the "cleaner if due care is taken.

As just described, my machine is used to clean floors. 'If walls are to be. cleaned, a nozzle is put on a flexible hose and the cap I of the appended cleaning, much as above described.

Modifications in detail within the scope claims may be resorted to without departing from the spirit of the invention or sacrificing any of its advantages.-

What I claim is 1. In a device of the class described, a

.nozzle, a pipe leading therefrom, a blower' at the upper end of said pipe, a bar extending downwardly at an angle to the said pipe and connected therewlth, a rod' connecting the lower ends of said pi e and bar, a flexible pipe connected to the lower casing, and a filter mounted between the firstmentioned pipe, the rod and the bar and into which the end of said flexible pipe discharges.

2. In a device of the class described, a nozzle, an inclined pipe leading therefrom, a bar supporting the upper end of said pipe, a blower mounted u on and connected with the upper end of said pipe, a rod connecting the lower end-of said pipe with the lower end of said bar, a filter mounted'on said rod and bar in the space inclosed by said pipe, a' pipe connected with the rod and bar, an casing of the blower and emptying into said filter.
